GI 3 Flashcards
Patients with achalasia are at increased risk of what
Esophageal cancer (usually SCC) (stasis and fermentation cause mucosal inflammation, epithelial hyperplasia and dysplasia)
Splenic vein thrombosis clinical features
history of chronic pancreatitis (splenic vein runs along posterior surface of pancreas so chronic inflammation can lead to thrombosis) + *isolated gastric varices (near gastric fundus only, never esophageal varices)
- variceal hemorrhage + epigastric pain
Management of splenic vein thrombosis
splenectomy
what is non-ulcer dyspepsia?
Functional dyspepsia (diagnosis of exclusion)
Next step after cirrhotic with mass on US + elevated AFP
IF less than 1 cm – repeat US in 3 months
IF greater than 1 cm – MRI liver with contrast (better sensitivity and specificity than CT for differentiating malignant nodule from regenerative nodules)
Management of diarrhea after ileal resection
cholestyramine (ileal resection leads to bile salt malabsorption and thus can’t absorb fats or fat-soluble vitamins. cholestyramine binds to bile acids)
Initial management of non-GERD-sounding dyspepsia (without alarm features)
IF under ago 60 + NO compelling indication for EGD – h pylori testing
IF over 60 or compelling indication for EGD –> EGD
Boerhaave syndrome clinical features + imaging
- hx of vomiting + chest pain + often rapid development of pleural effusion
- subcutaneous emphysema + mediastinal air (described as “retrocardiac air shadow”)
Chronic diarrhea in patient with systemic sclerosis
SIBO (due to reduced peristalsis and intestinal dilation)
antibiotic for SIBO
rifaximin
Multiple stomach ulcers OR thickened gastric folds think
gastrinoma (zollinger-ellison syndrome)
gastrinoma (zollinger-ellison syndrome) diagnosis
serum gastrin level
PBC is
primary biliary cholangitis
sequela of PBC
- Metabolic bone disease (osteoporosis and/or osteomalacia)
- hepatocellular carcinoma
- malabsorption, fat-soluble vitamin deficiencies
Additional management of PBC
calcium and vitamin D supplementation
Initial step in hemodynamically unstable GI bleed
NOT PRBC transfusion (as per MKSAP) if Hgb WNL
initial steps in management of variceal bleed
- volume resuscitation
- IV octreotide
- abx (7 day course of prophylactic abx, even if cultures remain negative)
Management of IDA if initial c-scope and EGD are negative
- small bowel evaluation with capsule endoscopy
Appearance of biopsy in microscopic colitis
- mononuclear lymphocytic infiltrates (high levels of intraepithelial lymphocytes)
- abnormally thickened sub epithelial collagen band
other clinical features of microscopic colitis
- fecal urgency and incontinence
Pancreatic pseudocyst clinical features
- develop after pancreatitis episode commonly
- persistently elevated lipase after pancreatitis episode + abdominal fullness OR early satiety
Management of pancreatic pseudocysts
- nothing (most pseudocysts resolve spontaneously)
IBS features
- recurrent abdominal pain
- diarrhea alternating with constipation
First step in workup of IBS
rule out red flags (Bleeding, nocturnal symptoms or worsening abdominal pain, weight loss, abnormal labs)
Management of patient following up after an episode of diverticulitis
- colonoscopy (rule out malignancy AND assess severity of diverticulitis)
- indicated even if c-scope within the last 10 years
General pressure ulcer management
1) Nutritional support
2) Pressure relief measures (scheduled turning)
3) Rule out infection
Dressing for pressure ulcers
Stage 1 (intact skin, just localized redness) -- transparent film dressing Stage 2 (shallow, open ulcer) -- occlusive or semipermeable dressing (maintain moist wound environment) Stage 3 (full thickness skin loss) -- hydrocolloid (NO OCCLUSIVE IF FULL THICKNESS) Stage 4 (exposed bone, tendon, or muscle) -- wound closure
Management of Schatzki ring
- dilation + *acid suppression therapy
Most frequent complication of schatzki ring
recurrence (frequently reoccur)
Syndrome for hepatic vein thrombosis
Budd-Chiari
Acute Budd-Chiari clinical features
- young woman with *rapid onset abdominal pain + ascites + some underlying hyper coagulable disorder or trigger (HCC, OCP use, pregnancy)
Diagnosis of boerhaave syndrome
- CT or esophagography with gastrografin (similar to barium swallow but gastrografin is used)
Infected pancreatic necrosis management
CT-guided aspiration OR empiric abx (carbapenem)
IF no response to antibiotics – surgery
antibiotics for treatment of infected pancreatic necrosis
carbapenem or quinolone + metronidazole (anaerobe coverage and superior penetration into pancreatic tissue)
SAAG cutoffs
- 1 (portal HTN)
2. 5 (heart failure vs. cirrhosis)
treatment of chronic mesenteric ischemia
- surgery or stenting
acute mesenteric ischemia clinical presentation
- rapid onset periumbilical pain
treatment of acute mesenteric ischemia
- broad spectrum abx
- NG tube decompression
- surgery for infarction or perforation
Other PBC features
- significant fatigue + pruritus
- skin hyperpigmentation
- can have inflammatory arthritis
hemochromatosis vs PBC in terms of labs
hemochromatosis = hepatocellular injury pattern PBC = primarily cholestatic liver injury pattern
Alarm features of GERD that required EGD prior to PPI trial
- age over 50
- dysphagia
- weight loss
- anemia
- hematemesis, melena
- failure of PPI trial after a month
- not lack of response to OTC antacids
Initial evaluation of cirrhosis
EGD (initial varices screening)
Indications for SBP prophylaxis
1) prior episode of SBP
2) GI bleed
3) ascitic protein less than **1.5 if also impaired renal function or liver failure
4) Child-Pugh class C with bilirubin (greater than 3)
Age cutoff requiring EGD prior to h pylori testing
Over age 60 need EGD
other lab features of autoimmune hepatitis
- multiple circulating autoantibodies (ANA, anti smooth muscle, may have antimitochrondial in low titer, anti liver-kidney microsomal-1 antibody)
presentation of acute hep b
- serum sickness like syndrome (fever, poly arthritis, *urticaial skin lesions)
- can also present with fulminant liver failure
ischemic colitis clinical features
- abrupt onset abdominal pain followed quickly by hematochezia
- commonly in watershed areas (splenic flexure, rectosigmoid colon)
ischemic colitis vs. small bowel mesenteric ischemia
- mesenteric ischemia = typically AF severe pain without significant abdominal tenderness, hematochezia is a late complication
- ischemic colitis = early hematochezia
Initial evaluation of suspected ischemic colitis
CT with contrast, followed by colonoscopy
Definition + management of atypical + persistent anal fissures
- atypical = lateral or anterior, multiple, painless, very deep, recurrent, non healing, no improvement with treatment
- c-scope for evaluation of Crohn disease
presentation of external hemorrhoids
IF thrombosed – pain
IF nonthrombosed – typically painless
alcoholic hepatitis presentation
*fever
abdominal distension
other features I know about
Meds causing medication-induced esophagitis
- NSAIDS
- tetracyclines
- bisphosphonates
- iron supplements
- potassium chloride
Management of medication-induced esophagitis
- stop offending medication
- no need for EGD unless severe, atypical or persistent symptoms after 1 week)
postexposure prophylaxis for hep A
- vaccinate all household contacts (vaccine is more available than immune globulin and is easier to administer)
- immune globulin in children under age 1 and immunocompromised individuals
abdominal pain following colonoscopy think
- perforation at polypectomy site
* may also have fever OR chest OR scapular pain
Initial management of suspected abdominal perforation from colonoscopy
- STAT abdominal x-ray plain and upright
- IF negative but high clinical suspicion – CT with contrast
Acute hep B management
- supportive care (most adult patients will improve clinically and cldar the infection)
Presentation of proximal small-bowel obstruction
- vomiting
- *have less abdominal distension
Alternative causes of elevated lipase
- CKD
- DKA
- intestinal obstruction or ileus
Initial workup of SBO
- plain upright CXR + upright and supine abdominal films
Management of rectovaginal fistulas in IBD patients
IF asymptomatic – no treatment (most will heal spontaneously)
- prolonged antibiotics + anti-TNF inhibitors
- IF failed medical therapy: surgery
Modified triple therapy for patient with pencillin allergy
flagyl instead of amoxicillin
management of moderate to severe hypertriglyceridemia-induced pancreatitis
IF blood glucose is over 500 – start insulin drip to correct triglyceride levels
If glucose below 500 or severe pancreatitis – therapeutic plasma exchange apheresis
next step in patient with celiac features and positive serology
Endoscopy with biopsy to establish diagnosis OR cutaneous biopsy with dermatitis herpetiformis
next step in patient with celiac features and negative serology
IgA level
healthcare maintenance for celiac
- pneumococcal vaccination (associated with hyposplenism)
- screen for nutritional deficiencies and bone loss
cause of respiratory alkalosis in cirrhotics
- Increased minute ventilation (cause of which is unclear)
Next step after patient with h pylori is found to have a peptic ulcer
- obtain multiple biopsies ulcer to rule out malignancy (Peptic ulcer disease is strongly associated with gastric cancer and gastric MALT lymphoma)
features of lactose intolerance
- abdominal pain + bloating + flatulence
- secondary lactose intolerance can develop after acute infection or inflammation (destruction of lactase enzyme)
Evaluation of PUD for H pylori
*Even if negative biopsy, stilll need a second test (urea breath or stool antigen) after patient has stopped PPI for 1-2 weeks (significant false negatives due to bleeding, PPI, or abx)
When repeat endoscopy is indicated following diagnosis of PUD
*bleeding gastric ulcers
Eosinophilic esophagitis clinical features
young man + atopy + intermittent solid-food dysphagia
- commonly food bolus
Endoscopy in eosinophilic esophagitis
- furrows, concentric rings, eosinophilic microabscesses (whitish papules and exudates)
Treatment of eosinophilic esophagitis
- dietary modification
- topical steroids
Initial step in work up of suspected PSC
colonoscopy to rule out underlying IBD + colorectal cancer (significantly elevated risk)
